    And also, can does anyone know if Volcanic activity can be mentioned for the natural production of NO. I'm kicking myself for not getting lightning in the exam, but at the same time I know Volcanoes can produce many polluting gasses

    What did everyone write for the 2 equilibrium questions?

    I think I wrote for one of the equations the equilibrium moves to the right? I forgot but it was so that more CO2 (aq) was produced

    Then I said as more CO2 (aq) was produced the equilibrium moves the the left (forgot direction) for the other equation so more CO2 (g) was produced in the atmosphere

    I thought the equilibrium for both of them moved to the left?

    What did you guys put for in question 5 that question that asked for the propagation reaction of irradiated chlorine and methane to produce CCl4.

    I said CHCl3 + Cl• --> CCl4 + H•
    Not sure if I'm right though :/

    ideas on what the carbonyl and biradical formed from ozone and propene would look like?

    ethanal and CH3-O-O(unpaired electron) ?

    how many marks was this worth

    See i put a chlorine instead of the H radical because HBr doesnt normally split via homolysis but chlorine does...? I might be wrong

    For the stereo isomer one, I put Z-but-2-ene and E-but-2-ene

    I messed up on so much more though, just hope I don't lose anymore than 25 marks D:!
    Do you think theyd accept cis and trans but 2 ene?

    What did people write for the final propagation step to produce CCl4?
    I put CCl3• + Cl2 --> CCl4 + Cl• is that right?

    Where has the Br come from? The question was about irradiated chlorine and methane to produce CCl4 or something..
